Operation
6.4 Entering Operation Parameters
You can enter Operation parameters through the keypad or through the remote terminal, if the terminal is
enabled in the System Setup menu. Only the Amplitude value (using the Amplitude knob on the side of the
chassis) may be changed when an experiment is running.
When the System is in the Ready mode (e.g. after power-up or after a test or experiment is performed) it displays
the first page of the Parameter Entry menu. In the Parameter Entry menu, you can enter parameters for your
test or experiment. When a Line Select key for a parameter is available and may be selected, its LED is lit.
Entering Parameters from the Keypad
When in the Ready mode, you can press any available
Line Select
key on the front panel to select a parameter
for modification. There are a total of two (2) pages of parameters; use the Arrow Up or Arrow Down keys to
see more parameter choices on the display.
Use the number keys to key in a parameter value, and press
Enter
to store the value or accept the choice, or
press
Clear
to clear a stored numeric entry or to disable a choice and then press
Enter
to store the cleared or
disabled parameter value. The System will not accept parameter values that are out of the range of the system.
Once the parameters have been changed and stored, the experiment is ready to run with the new values.
6.4.1 Presets
Once you have a set of parameters stored for a given experiment, you can save that setup as a Preset. Up to 20
Presets may be saved, using the Save and Recall functions described in the following sections. Presets are saved
and recalled using a number, 01 to 20. Presets save all parameters for the setup except for the Amplitude param-
eter. Presets are saved until they are over-written or cleared, and are maintained in memory even if the system
is turned off or unplugged.
6.4.2 Remote Terminal entry
The Remote Terminal may be used to change any of the operation parameters (except for Amplitude). Instruc-
tions and commands that you use to enter parameters from the remote terminal are described in
Section 6.5,
Remote Computer or Terminal,
beginning on page 6-35.
Reviewing Parameters on the Remote Terminal
If you have disabled the front-panel keypad by sending a !KL from the remote terminal, only the
Start/Stop
and
Pause
keys are active. If both the keypad and the remote computer or terminal are active, the parameters
displayed on the front panel will be similar to those described in this section, but any values you enter on the
keypad will be updated at the remote computer or terminal only when you request them by issuing the Recall
Parameters (!RP) command. See
Section 6.5, Remote Computer or Terminal,
beginning on page 6-35 for more infor-
mation.
